Were you looking for information about Down Syndrome? Downssyndrome is a common misspelling of Down syndrome.
Down syndrome is a disorder in which the presence of an extra 21st chromosome causes delays in the way a child develops, both physically and mentally. It is the most frequent genetic cause of mild to moderate mental retardation and associated medical problems. People with the condition are also at an increased risk for developing eye problems, seizure disorders, and Alzheimer's disease. Life expectancy for people with Down syndrome has increased substantially; today, it is common for a person with this condition to live to age 50 and beyond.
